D: y = 2x + 3

kropot72 · Answer

The product of the slope of the given equation and the slope of the equation that is perpendicular must equal -1.
Let the slope of the equation that is perpendicular = m
2 * m = -1 .............(1)
As a first step in the solution, can you solve equation (1) ?

O.o i'm cunfused :P

anonymous · Answer

Is the answer D? I'm not good with slopes

kropot72 · Answer

To solve 2m = -1 divide each side of the equation by 2.
$$\frac{2\times m}{2}=-\frac{1}{2}$$
Can you see the value of m now?
